如何将变量从一个函数传递到另一个函数或组合函数

时间：2016-10-12 作者：ERDFX

我有两个功能：

第一个-处理所有自定义程序选项第二个-从这些选项生成内联样式在第一个函数中，我设置变量，从中创建自定义程序设置和控件，如下所示：

function im_customize_register( $wp_customize ) {

//Custom Sections

$wp_customize->add_section(
    \'body\',
    array(
        \'title\'     => __(\'Body Settings\', \'impressive\'),
        \'priority\'  => 200
    )
);

//Styles

$bg_color = \'background-color:\';
$max_width = \'max-width:\';

$styles = array();

$styles[] = array(
  \'slug\'=>\'body_bcolor\', 
  \'default\' => "#F1F2F1",
  \'label\' => __(\'Body Background Color\', \'impressive\'),
  \'css_class\' => \'body\',
  \'attribute\' => $bg_color,
  \'section\' => \'body\',
  \'type\' => \'color\'
);
$styles[] = array(
  \'slug\'=>\'max_container_width\', 
  \'default\' => \'1440\',
  \'label\' => __(\'Maximal Container Width\', \'impressive\'),
  \'css_class\' => \'.header\',
  \'attribute\' => $max_width,
  \'section\' => \'body\',
  \'type\' => \'number\'
);

foreach( $styles as $style ) {

  $wp_customize->add_setting(
    $style[\'slug\'], array(
      \'default\' => $style[\'default\'],
      \'type\' => \'option\', 
      \'capability\' => 
      \'edit_theme_options\'
    )
  );

 if ( $style[\'type\'] == \'color\' ) {
  $wp_customize->add_control(
    new WP_Customize_Color_Control(
      $wp_customize,
      $style[\'slug\'], 
      array(\'label\' => $style[\'label\'],
      \'section\' => $style[\'section\'],
      \'settings\' => $style[\'slug\'],
      \'type\' => $style[\'type\'])
    )
  );
  } elseif ( $style[\'type\'] == \'image\' && $style[\'section\'] == \'header_image\' ) {
    $wp_customize->add_control(
        new WP_Customize_Header_Image_Control(
        $wp_customize,
        $style[\'slug\'], 
        array(\'section\' => $style[\'section\'],
        \'settings\' => $style[\'slug\'])
    )
  );
 } else {
  $wp_customize->add_control(
    new WP_Customize_Control(
      $wp_customize,
      $style[\'slug\'], 
      array(\'label\' => $style[\'label\'],
      \'section\' => $style[\'section\'],
      \'settings\' => $style[\'slug\'],
      \'type\' => $style[\'type\'])
    )
  );

  }

}

}
add_action( \'customize_register\', \'im_customize_register\' );
在第二个函数中，我需要键入相同的变量，以便脚本生成内联CSS：

function im_custom_style_create() {

wp_enqueue_style( \'im_custom_style\', get_template_directory_uri() . \'/css/im_custom_style.css\' );

$custom_css = \'\';

$bg_color = \'background-color:\';
$max_width = \'max-width:\';

$measurement_unit = \'\';

$styles = array();

$styles[] = array(
  \'slug\'=>\'body_bcolor\', 
  \'default\' => "#F1F2F1",
  \'label\' => __(\'Body Background Color\', \'impressive\'),
  \'css_class\' => \'body\',
  \'attribute\' => $bg_color,
  \'section\' => \'body\',
  \'type\' => \'color\'
);
$styles[] = array(
  \'slug\'=>\'max_container_width\', 
  \'default\' => \'1440\',
  \'label\' => __(\'Maximal Container Width\', \'impressive\'),
  \'css_class\' => \'.header\',
  \'attribute\' => $max_width,
  \'section\' => \'body\',
  \'type\' => \'number\'
);

foreach( $styles as $style ) {

if ( $style[\'attribute\'] == $max_width ) { $measurement_unit = \'px\'; }

if ( get_option( $style[\'slug\'] ) == true ) { $custom_css = \'\' . $style[\'css_class\'] . \' { \' . $style[\'attribute\'] . \' \' . get_option( $style[\'slug\'] ) . $measurement_unit . \'; } \'; };

wp_add_inline_style (\'im_custom_style\', $custom_css);
}

}
add_action( \'wp_enqueue_scripts\', \'im_custom_style_create\' );
我的问题是：有没有办法通过$styles 从第一个函数到第二个函数，或者没有一个函数可以将这两个函数组合起来。我试着把它们结合起来，但我没能让魔法发生。

最简单的方法有两种。

通过函数调用来实现。

使变量成为全局变量。

第一步是这样做的：

function my_func() {
    $styles = \'stuff\';

    second_func($styles);
}

function second_func($styles) {
    // do something with $styles
    var_dump($styles);
}
第二种方法如下：

// Set global variable
$GLOBALS[\'styles\'] = \'stuff\';


// Call it anywhere else
global $styles;

编辑：见下文。

global $styles;

$styles = array(
  array(
    \'slug\'=>\'body_bcolor\', 
    \'default\' => "#F1F2F1",
    \'label\' => __(\'Body Background Color\', \'impressive\'),
    \'css_class\' => \'body\',
    \'attribute\' => \'background-color:\',
    \'section\' => \'body\',
    \'type\' => \'color\'
  ),
  array(
  \'slug\'=>\'max_container_width\', 
  \'default\' => \'1440\',
  \'label\' => __(\'Maximal Container Width\', \'impressive\'),
  \'css_class\' => \'.header\',
  \'attribute\' => \'max-width:\',
  \'section\' => \'body\',
  \'type\' => \'number\'
  )
);


function im_customize_register( $wp_customize ) {
global $styles;
//Custom Sections

$wp_customize->add_section(
    \'body\',
    array(
        \'title\'     => __(\'Body Settings\', \'impressive\'),
        \'priority\'  => 200
    )
);

foreach( $GLOBALS[\'styles\'] as $style ) {

  $wp_customize->add_setting(
    $style[\'slug\'], array(
      \'default\' => $style[\'default\'],
      \'type\' => \'option\', 
      \'capability\' => 
      \'edit_theme_options\'
    )
  );

 if ( $style[\'type\'] == \'color\' ) {
  $wp_customize->add_control(
    new WP_Customize_Color_Control(
      $wp_customize,
      $style[\'slug\'], 
      array(\'label\' => $style[\'label\'],
      \'section\' => $style[\'section\'],
      \'settings\' => $style[\'slug\'],
      \'type\' => $style[\'type\'])
    )
  );
  } elseif ( $style[\'type\'] == \'image\' && $style[\'section\'] == \'header_image\' ) {
    $wp_customize->add_control(
        new WP_Customize_Header_Image_Control(
        $wp_customize,
        $style[\'slug\'], 
        array(\'section\' => $style[\'section\'],
        \'settings\' => $style[\'slug\'])
    )
  );
 } else {
  $wp_customize->add_control(
    new WP_Customize_Control(
      $wp_customize,
      $style[\'slug\'], 
      array(\'label\' => $style[\'label\'],
      \'section\' => $style[\'section\'],
      \'settings\' => $style[\'slug\'],
      \'type\' => $style[\'type\'])
    )
  );

  }

}

}
add_action( \'customize_register\', \'im_customize_register\' );


function im_custom_style_create() {
global $styles;

wp_enqueue_style( \'im_custom_style\', get_template_directory_uri() . \'/css/im_custom_style.css\' );

foreach( $styles as $style ) {

if ( $style[\'attribute\'] == $max_width ) { $measurement_unit = \'px\'; }

if ( get_option( $style[\'slug\'] ) == true ) { $custom_css = \'\' . $style[\'css_class\'] . \' { \' . $style[\'attribute\'] . \' \' . get_option( $style[\'slug\'] ) . $measurement_unit . \'; } \'; };

wp_add_inline_style (\'im_custom_style\', $custom_css);
}

}
add_action( \'wp_enqueue_scripts\', \'im_custom_style_create\' );
